The improved rock breaking efficiency of an annular-groove PDC bit
Journal of Petroleum Science and Engineering, 2019Abstract To solve a major problem faced by drilling technicians, that of how to improve rock breaking efficiency in complex strata, this paper introduces a polycrystalline diamond compact (PDC) drill bit with a special structure. Static-pressure breaking tests show that the breaking work ratio of a single tooth on a ridge is much smaller than that on

THE EFFECT OF ROCK BIT CUTTING STRUCTURE ON ROCK BREAKING EFFICIENCY
Proceedings of International Meeting on Petroleum Engineering, 1986ABSTRACT A study of the effect of rock bit cutting structure on rock breaking efficiency was made with full scale bits for soft to medium formations on a laboratory testing rig. An analysis of the relationship between rock breakage and cutting structure based on the drilling rate, bottom hole pattern and operating parameters revealed the

ABSTRACT: High-pressure jet drilling technology is an efficient and clean drilling speed increase technology, which has been widely used in middle and upper strata drilling. However, with the global oil and gas exploration and development gradually into deep water and deep depth, the high confining pressure ...
